This invention relates generally to the class of hsrdwere, end hasparticular reference to an improved nut for threadedly enguging sthreaded stem, bolt, spindle or the like.

As an oh'ect, the invention comprehends an improve nut which isconstructed in such s manner as to he engaged by s wrench with greaterfecility endmore security than ordinery types of nuts that are now ingeneral use end on the market.

The invention further aims to provide e nut which may be turned by ewrench while imparting lesser strains and stresses to the wrench and inwhich the nut may be disposed in closer proximity to a, well or cornerof structure then the usual type or" nuts.

More specifically, the invention contempletes nut having non-parallelside faces end truncated spores at the juncture of seid side faces,which truncated spores are formed with wrench receiving recesses withinwhich least two of said recesses, the wrench preferehly engage forturning the nut.

@ther objects of the invention reside in t e comparative simplicity ofconstruction mode of use of the nut, the economy with v rich it heproduced end the general eiuciency derived therefrom.

With shove recited and other objects view, reference is to the followingdescr ntion end smompenying drawing, in which there is exhibited oneexample or emhodimen't the invention, while the claims define tne sctuulscope of the sense n the i as side view t erect,

cross sectional view ti erer oximutely on the line in- S in i lgure l.

, Referring to the drawing" by characters of reference, nut consists ofat body which is provided with e plurality of major side feces disposedin non-parallel relution end en single to such other. Preferably, the

nut is in :lorm of uneouiluterel triungle us illustrated, elthough is tohe understood that it is not necessarily restricted to this shape. Thenut body 5 is formed with truncated upexes 7 which present minor sidefaces disposed parallel to and opposite the major faces of the nut, andsaid truncated spexes 7 are formed with wrench jaw receiving recesses ornotches 8 which preferably exceed a semi-circle and which are desi nedto re ceive the similarly formed jaws oi a wrench. ln practice, at leasttwo of said recesses will preferubly receive a, pair of wrench jaws forthe purpose of turning the nut and, consequently, the Wrench shankproper will engage with one of the major side faces 6 whereby a freepoint engagement is established at at point at one side of the axis ofrotstion of the nut, thus securely establishing a connection between:the wrench and the nut end subjecting the wrench to lesser strain orstress than is produced on a wrench with the ordinary types of nuts. ltwill he further apparent that due to the shape of the nut, it may beinstalled on a bolt or threaded stem which is set closer to a, well,corner or angle of a structure. it is further apparent that F thenotches or recesses 8 which extend com pletely throughout the depth orthicliness of the nut, may be employed to receive therethrough u pinscrew or other device en" chored in s stationery structure which willserve to lock the nut against retrograde movement,

il/hut is claimed is:

i. As a new erticle of msnuilscture, a nut having non-parallel sidefeces end truncated spores the juncture of the side feces, seidtruncated spores having wrench receiving recesses,

As new article 01" manufacture,

liuving nonperellel side and truncated upexes at the juncture of theside feces, truncated spares having wrench receiving; recesses extendingthroughout the thiclniess oi the nut.

3. As s new article of manufacture, it nut in the form of en equilateraltriangle having truncated speues'provided with wrench receivingrecesses.

l. As anew article of manufacture, it nut in the form of nu equilsterultriangle hsv- 2 naemsee ing truncated apexes provided with wrenchrecelvmg recesses exceedmg a seml-cn'cle.

5. As a new artlcle of manufacture, a nut in the form of an equilateraltriangle having truncated a exes presenting minor faces parallel to t epp0s1te maJor faces of the nut, said minor faces provided with wrenchreceiving recesses.
